Dear friends.
I want to use Vim + Spice 2G6.
I have made circuit1.cir text file in Vim and stored it in my drive.
After that when I open spice command prompt, and after writing spice < circuit1.cir and after pressing enter key, it display the window as attached here.

So I am not getting the output as displayed in DC.pdf chapter 2, SPICE SIMULATION.
